- the steel cord 1 becomes brittle than the original by heating in this vulcanization process. Therefore, when the cushioning material 4 is not provided, the shearing stress F acting between the core strand 2 and the side strand 3 causes the shear breakage to be dominant as the failure mode of the steel cord 1 and the cord strength is reduced. To do. In the present invention, even if the steel cord 1 becomes brittle by heating in the vulcanization process, the acting shear stress F is absorbed to some extent by the buffer material 4 and reduced. This makes it possible to suppress a decrease in code strength.
- the diameter of the steel cord 1 can be reduced. Therefore, it contributes to the weight reduction of the steel cord 1 and eventually the rubber product.
- the bending resistance durability against repeated bending is improved by reducing the diameter of the steel cord 1.
- the basis weight of the nonwoven fabric is preferably, for example, 10 g / m 2 or more and 40 g / m 2 or less. If the basis weight is less than 10 g / m 2 , the buffering effect of the shear stress F becomes small and it is difficult to sufficiently suppress the decrease in the cord strength. If the basis weight is more than 40 g / m 2 , the adhesion between the steel cord 1 (core strand 2) and the vulcanized rubber tends to be adversely affected. Further, in the vulcanization step, the unvulcanized rubber is less likely to penetrate between the core strand 2 and the side strand 3.
- the thickness is preferably 0.05 mm or more and 0.5 mm or less, for example. If the film thickness is less than 0.05 mm, the buffering effect of the shear stress F becomes small and it is difficult to sufficiently suppress the decrease in the cord strength. If the film thickness exceeds 0.5 mm, the adhesiveness between the steel cord 1 (core strand 2) and the vulcanized rubber tends to be adversely affected. Further, in the vulcanization step, the unvulcanized rubber is less likely to penetrate between the core strand 2 and the side strand 3.
- the heating temperature in the vulcanization process is preferably set to a temperature equal to or higher than the melting point of the buffer material 4.
- the unvulcanized rubber passes through the buffer material 4 and relatively easily penetrates into the gap between the core strand 2 and the side strand 3.
- a resin film is used as the buffer material 4, it is preferable to provide through holes with an appropriate density in order to ensure the permeability of the unvulcanized rubber.
- the heating temperature in the vulcanization process varies depending on the size of the rubber product, the heating temperature when vulcanizing the rubber product is generally 140 ° C. or higher and 160 ° C. or lower. Therefore, if the melting point of the buffer material 4 is 160 ° C. or less, the buffer material 4 can be melted by heating in the vulcanization step.
- the rubber product manufactured according to the present invention is not limited to the conveyor belt 8, and various rubber products in which the steel cord 1 is embedded as a reinforcing material such as a tire, a rubber hose, a marine hose, and a fender can be exemplified. It is particularly preferable to apply the present invention to the manufacture of a conveyor belt 8 or a heavy duty tire (such as a large construction machine tire) in which the importance of the cord strength of the steel cord 1 is relatively high.
- a steel cord (Examples 1 to 5) having the same structure as that illustrated in FIG. 1 and a steel cord (conventional example) obtained by removing a buffer material from the steel cord are each subjected to the same conditions under an unvulcanized rubber (NR / Embedded in SBR) and vulcanized for 20 minutes. After vulcanization, the steel cord was taken out as a test sample, and cord strength, cut elongation, and air permeability were measured. The results are shown in Table 1.
- Table 1 shows the data before vulcanization of the steel cord of the conventional example as a reference example.
- the cord outer diameter of each test sample was 4 mm, and a polypropylene nonwoven fabric (melting point: 160 ° C.) was used as the buffer material. This nonwoven fabric cushioning material is spirally wound around the outer peripheral surface of the core strand.
- Examples 1 to 5 can suppress a decrease in cord strength as compared with the conventional example. It can also be seen that the air permeability has a level with no practical problem.
Abstract
Description
それぞれの試験サンプルをJIS G3510:1992に準拠して破断するまで長手方向に引張り、破断時における荷重をコード強力、破断時における伸びを切断伸びとした。 [Strong cord] [Cutting elongation]
Each test sample was pulled in the longitudinal direction until it broke in accordance with JIS G3510: 1992. The load at break was defined as the cord strength, and the elongation at break was defined as the cut elongation.
それぞれの試験サンプルをオーストラリア規格(AS-1333)による「空気透過性試験方法」に準拠して、試験サンプルの長手方向の一端部から100kPaの空気圧を圧入し、空気圧を圧入した後の60秒間に他端部側に透過した空気圧を測定し、その結果を表1に記載した。この空気圧が小さいほど耐空気透過性に優れ、スチールコードに対するゴム浸透性が優れていることを示す。尚、5kPa未満であれば十分な耐空気透過性を有していると判断できる。 [Air permeability]
In accordance with the “air permeability test method” according to the Australian standard (AS-1333), each test sample was injected with air pressure of 100 kPa from one end in the longitudinal direction of the test sample, and 60 seconds after the air pressure was injected. The air pressure permeated to the other end side was measured, and the result is shown in Table 1. The smaller the air pressure, the better the air permeation resistance and the better the rubber permeability to the steel cord. In addition, if it is less than 5 kPa, it can be judged that it has sufficient air permeation resistance.
